Abstract

Appareil débitant un fluide gazeux chaud. La chambre de prémélange 10 est alimentée en gaz combustible en 14 et en air primaire en 15. La sortie de flamme est à l'air libre en 17 et entourée par une entrée annulaire 22 d'air secondaire. L'extrémité aval de la chambre de prémélange 10 comporte un divergent brusque 16 suivi d'une grille appropriée 17, ce qui a pour effet de fractionner la flamme en une pluralité de petites flammes courtes et distinctes. Applications : rétraction des matières plastiques et autres traitements par un fluide gazeux chaud.
